2.1. Apply sufficient epoxy to the centreline marked in Stage 1

2.2. Slide the tube fully into the wing

2.3. Wipe off any excess epoxy

Irvine Tutor 40 II

Once the glue has cured, trial fit the second wing panel onto the first, making sure that the two panels meet without an excessive gap. File the end of the tube if necessary to ensure that the wing panels meet. Now apply plenty of epoxy to the wing root rib and the joiner tube as shown. Use 30 minute or 1 hour epoxy to give yourself extra working time. Slide the two wing panels together. Epoxy should ooze from the joint and the excess can be removed with a cloth or tissue before it cures. Use adhesive tape to hold the two panels together as the glue cures ensuring that the panels are correctly aligned.

Stage 3

3.1. Apply plenty of adhesive

3.2. Slide the second wing panel into place

FITTING THE AILERON SERVO

3.3. Ensuring a close fit, use tape to ensure alignment while the glue cures

The Irvine Tutor 40 II is suitable for both Electric Motors and I.C. Engines. The following sections cover I.C. Engine installation and Electric Power.

Irvine Tutor 40 II

I.C. Engine Installation

I.C. ENGINE FITTING

Stage 1Prepare the fuel tank by attaching a length of clunk tubing to the unbent tube on the tank bung. Using the tank as a guide, trim the clunk tubing so that when connected to it, the clunk is free to move without touching the rear of the tank. Now insert the bung in the tank with the bent vent pipe to the top. Tighten the retaining screw to seal the bung in position.

1.1. Cut the clunk tube to length

1.2. Tighten the assembly screw

Stage 2Holding your engine centrally in position on the pre-fitted engine mount, mark the position of the mounting screw holes. Pilot drill (2mm) the moulded engine mount as shown. Attach the z-bent throttle pushrod end to the engines throttle arm, then feed the pushrod into its tube in the firewall. Attach the engine to its mount using the four self tapping screws supplied.

2.1. Mark the position of the mounting holes

2.2. Pilot drill the mount

Stage 3Attach two lengths of fuel tubing to the tank - one for feed and one for pressure. Unlatch the hatch on the underside of the model and slide the tank into position ensuring the tubes are not kinked as they pass through the bulkhead. Retain the tank with the two velcro straps already installed in the fuselage. Refit the hatch. It is a good idea to glue a small block of wood to the tray behind the tank tp prevent it sliding backwards.

2.3. Fit the throttle pushrod

2.4. Attach the engine

3.2. Retain it with the two velcro straps

3.3. Refit the hatch

3.1. Slide the tank into its bay

Stage 44.1. Fit a pushrod connector to your servo horn

Prepare your throttle servos horn by fitting a pushrod connector as 4.2. Install the throttle servo shown. Do not over-tighten. Apply a small drop of cyano on the nut to secure. Install the rubber grommets and bushes supplied with your servo, then pilot drill the servo tray and screw the servo in position using the screws supplied with your radio. Slip the throttle pushrod connector over the pushrod and re-fit the throttle servo horn. Do not fully tighten the grubscrew yet as the throttle is adjusted later. 10 Irvine Tutor 40 II

4.3. Slide connector over the pushrod then re-fit the horn

I.C. Engine Installation

Stage 5Connect the fuel feed pipe to the engines carburettor or remote needle valve as shown here. Connect the pressure pipe to the engines silencer, then fit the silencer with the screws supplied with the engine.5.1. Connect the fuel tube 5.2. Connect the pressure tube and install the silencer

Remove your engines prop nut and washer. Install the spinner backplate followed by your propeller. Use the moulded pegs to align the propeller so that when the propeller is in the correct position, the spinner cut-out will align correctly with the propeller. Re-fit your prop washer and nut, then tighten. Fit the spinner nose with the two screws supplied.

Stage 6

6.1. Fit the spinner backplate

6.2. Fit your propeller and tighten

6.3. Re-fit the spinner nose

It is vitally important that the throttle operates correctly and does not bind at either end of its travel. Switch on the radio and centralise the throttle stick. Holding the throttle barrel at its mid throttle position, nip the grub screw tight in the pushrod connector. Use your transmitters end point adjustment - EPA/ATV - (or adjust mechanically) so that the throttle opens and closes as shown in the diagrams below

Electric Motor Installation

ELECTRIC MOTOR FITTING

Stage 1Remove the pre-fitted IC engine mount (4 bolts with spring washers and washers). The mount and bolts are no longer required but retain the washers. Remove the battery access hatch and remove the captive nuts from behind the engine mounting bulkhead. These will be re-used to fit the electric motor.

1.1. Remove the engine mount screws

1.2. Remove the factory-fitted captive nuts

Stage 2By using the large fuel tank neck location hole as a centre, mark the positions of the mounting screws on the bulkhead using the mounting plate as a guide. If you are fitting the recommended KMS motor (quantum 4120/05), the two upper holes for the IC mount are re-used and only the lower ones need to be drilled. Drill the mounting holes in the bulkhead using a 5mm drill.

2.1. Mark the bulkhead for the motor mount

2.2. Drill the bulkhead for the mounting screws

You will need to supply spacing stand-offs for the motor you have chosen. Motor lengths and fitting dimensions vary a lot from make to make. For the KMS Quantum 4120/05 motor they need to be 35mm long, 12mm wide with a 4.1mm internal bore. For these spacers, you will need 45mm M4 bolts. You can re-use the washers and spring washers from the original mount. An optional spacer/screw kit is available with all that you need for the KMS motor. Fix the captive nuts in the back of new bulkhead holes and fit the motor using the screws and washers detailed above (or appropriate to your motor). Tighten the bolts so that the captive nuts are fully home in the bulkhead. Do not let the wood of the bulkhead be crushed.

Stage 3

3.1. Fit the motor mount to the motor

3.2. Fit the motor to the bulkhead

Stage 4Fit the backplate of the spinner to the propeller driver, then the propeller, washer and nut. Note The trailing edge of the propeller should be in contact with the small moulded posts on the backplate. This is to align the propeller with the cutouts in the spinner cone. Make sure the main fixing nut is securely tightened. Fix the spinner cone to the backplate with the two self tapping screws provided with it.

Stage 5Complete the motor installation by feeding the motor wires through the hole in the bulkhead and into the battery bay.

to use some more Velcro tape on the face of the tray and the underside of the battery (just 25mm is enough) to stop the battery sliding. We also recommend fixing a couple of balsa spacer blocks to the rear of the bulkhead to prevent the battery touching the captive mounting nuts and bolts if it moves forward. Set the operation of the motor/ESC by reference to the ESC instructions.

5.1. Motor wires go through the bulkhead

Stage 6Mount the ESC (Electronic Speed Controller) to the fuselage side using adhesive foam tape. The battery is retained in the tray by the Velcro straps provided. It is a good idea

4.1. Fit the spinner backplate and propeller

6.1. Attach your ESC with double sided tape

Irvine Tutor 40 II

COMPLETING THE TUTOTR 40 II Your radio switch (or if you are using an ESC with a switch) can now be mounted. The radio tray has a pre-cut slot should you wish to mount the switch internally and operate it with a bent wire through the fuselage. The simplest way of fitting the switch is simply mounting it through the left-hand fuselage side (on the opposite side to the exhaust). Using the switch plate as a guide, mark and drill the mounting holes. Now cut a suitable slot for the switch. Mount using the screws supplied with the switch.

Stage 31

31.1. Use the switch as a guide for cutting

31.2. Fit the switch in the fuselage side

Stage 32Locate the pre-drilled holes for the wing mounting dowels. Using a sharp knife, trim the covering away so the dowels can be pushed through the fuselage sides. Ensuring they are centrally located in the fuselage, run some medium super glue around each to secure.

32.1. Trim away the covering

32.2. Insert the wing dowel

Stage 33 To ensure that the trailing edge of the wing is not crushed by the wing mounting bands, two plywood reinforcement plates are used on the top surface. Holding the first plate in position on the wing with its rear aligned to the trailing edge, mark its shape on the surface of the wing using a water-soluble/non-permanent felt pen. Trim away the covering inside the marked line and glue the plate in position. Repeat for the second plate.

33.1. Mark the position of the first plate

33.2. Trim away the covering

Stage 34Wrap your receiver and battery (if using a separate battery for the 33.3. Repeat for the second side receiver) in dense foam packing and install in the fuselage under the tank. The batterys final position will be determined once the model has had its balance point checked.33.4. The completed wing

FINAL R/C SETUP

Stage 35Before starting the final set-up of the Tutor 40 II, switch on the radio and ensure that all trims are in their neutral positions. Check that the ailerons, elevator and rudder are centred. If any adjustments are needed, do this by unclipping the appropriate clevis and turning it clockwise to shorten the linkage or anti-clockwise to lengthen it. Only when each control surface has been centred mechanically should you begin adjusting the surface movements (or control throws). Irvine Tutor 40 II 13

34.1. Receiver battery wrapped in foam

34.2. And installed in tank bay

FINAL R/C SETUP - CONTINUED

Stage 36Now confirm the control surfaces are moving in the correct direction. Use the servo reversing switches on your transmitter to reverse the direction of a servo if necessary. The most popular transmitter mode (with the throttle and rudder on the left, with the ailerons and elevator on the right) is shown here.

ELEVATOR UP

ELEVATOR DOWN

Stage 37For the Tutor 40 II to fly well, its control surfaces need to move the correct amount. Too little movement and the model will be slow to react to your commands; too much and it will be oversensitive and difficult to control. If you have a modern computer radio, then it is possible to finetune the settings to suit you. But you should always set the model up mechanically correctly first. The movement, or throw of a surface is always measured at the trailing edge (the rear) of the surface and usually at its widest point. You can use a ruler or a proprietary gauge to do this. Adjust the linkages by moving the positions of the pushrods in their control horns(as shown here) to achieve the following control surface throws:-

Irvine Tutor 40 II

BALANCING THE MODEL Attach the wing using all the rubber bands supplied, (although we do recommend the use of white, silicon bands as they resist fuel and last longer. You can obtain them from your local model shop) stretched diagonally across the wing dowels. Now hold the model on your fingertips at a position 80mm back from the the leading edge of the wing. The model should balance slightly nose down. The receiver battery (or flight battery if flying with electric power) can be moved slightly forwards or rearwards to achieve this balance point without adding any extra weight. The importance of achieving the correct balance point cannot be overstated. It is essential the model balances correctly before attempting to fly it! This check should always be carried out with the flight battery in place when flying it with electric power and with the tank empty if flying it with I.C. engine power. FLYING THE TUTOR 40 II Always fly the model in a safe and suitable location, away from houses, people and power lines. It is always recommended that you enlist the help of a competent pilot and fly at a recognised club. Before flying, check that the controls move in the correct direction, and the correct amount. Always charge your radio equipment in accordance with the manufacturers recommendations and ensure that you are familiar with the operation of your engine or motor before attempting to fly.

Stage 38

Stage 39

SAFETY Always keep your hands and clothing clear of the spinning propeller. Fly safely and always maintain your model in good condition by thoroughly cleaning the airframe between flying sessions and checking its condition before flying and especially after a heavy landing. NOTES
